T0 all whom it may concern.-

Beit knownthat I, HENRY G. VCIGHT, a citizen of the United States, residing at New Britain', in the county of vHartford and State of Connecticut, have invented certain new and useful Improvements in vKnockdown Brackets, of which the following is a specilication. i y

Myinvention relates to improvements in knockdown brackets; and the'objects-of my improvement are simplicity and economy in construction and efficiency and convenience In the accompanying drawings, Figure 1 is a central vertical section of thevwall and shelf plates of my bracket with aside elevation of the brace. Fig. 2 is a detached .plan View showing the upper end of the wall-plate. Fig. 3 is a front elevationof the wall-plate on Fig. 4 is a reverse plan View of the shelf-plate. Fig. 5 is a rear end view of the, shelf-plate on the same scale as Fig. 1. Fig. 6 is a rear elevation of the complete bracket in a slightly-modified form on a reduced scale. Fig. 7 is a vertical section of the corner portion ofthe said bracket on the line x, Fig. 6, the scale being the same as in Fig. 1. Fig. 8 is a-pl'an view ofthe said corner portion. p j

A designates the wall-plate, B the shelfplate, and C the brace. Y YThe body portion of these parts may be of any ordinary form. They are intended to be formed of lsheet metal and may be provided with any ordinary-or desired form of strengthening-beads. In the preferred form the upper end ofthe wall-plate A' is provided with front straps 9 10, swaged or pressed forwardly from thel plate, and with a rear strap 11 in the plane of the plate proper, lso as to form a vertical'socket to receive the tongue 12 on the rear end of the shelf-plate B. I prefer to make the upper edge of the front strap 9 a little below the extreme upper end ofthe wall-plateA, wherebyl the corners 13 of the The wall and shelf plates may be provided with any desired nnmberof screw-holes 15, which may be countersunk in anyproper manner.

tongue is in place registers withthe upper one ofthe screw-holes 15 of the shelf-plate, So that when a screw is passed therethrough the said screw will positively lock the wall andshelf plates together.' The wall and shelf plates in the particular form shown are each provided with two brace4 mortises or slots 16 and 17,

and the brace C'is provided at each end with a tenon 18 and hooked lug 19. The endsof the brace stand at a right angle to each other,l and the hooked lug 19 at the lower end of the brace projects downward1y,while that at the up' per end of the brace projects outwardly, or, in other words, both of the hooked lugs project outwardly from the corner formed by the junction of the wall and shelf plates. The tenons 18 substantially fill the mortises or slots lintheiwall and shelf p1ates,`while the hooked'lngs at'th'eir longest part are of a length that will pass through` the mortises or slots 17, so that they ymay be hooked to the wall and shelf plates by engaging the metal j' at the outer ends of the mortises or slots 17, the projecting portion of the said hooked lugs being on the inner side ofthe said plates, as shown in Fig. 1.

The bracket shownin Figs. 6, 7, and 8 is the same as in Figs. -1 to v5, excepting that there is no rear strap or 'wallv for the socket of the tongue l2, that the screw-holes 15a are countersunk by swaging, so that a bur 2O is formed at the rear on the metal around the said screw-holes, and that the screw-hole 14C:t in the said tongue is countersunk on its front face, so as to receive the bur 2O of the upper one of the screw-holes of the wall-plate, A,with

which upper hole the screw-hole lata` registers.v

the wall-plate before the bracketis screwed to the wall. f `In order to assemble either form of the bracket herein shown, the lower end of the brace is locked to the wall-plate by passing the hooked lug 19 through the mortise or slot 17, then forcing it down to engage the metal at the lower end of the said slot, and then pushing the tenen 18 into the mortise or slot 16 to lock the hooked lug. The tongue 12 of the shelf-plate is then inserted in its socket; but the inner end of the shelf-plate is left a little higher than its locked position until after the shelf-plate has been crowded rearwardly far enough to enter the hooked lug 19 through the mortise or slot 17 of the shelf-plate. After the said lug passes through the said slot the shelf-plate is moved forwardly to engage the hooked lug with the metal at the outer end of the said slot and to bring the tenon 1S under the mortise 16. The rear end of the shelf-plate is then lowered into its inal 'position to positively lock the parts in place, as shown in Fig. 1. The parts are thus firmly held together, and the bracketl is ready for being screwed to the wall in the ordinary manner, in doing which one of the screws passes through the registering holes of the wall-plate and tongue 12 of the shelfplate, so that the two plates are firmly locked together. The bracket may be knocked down again after removing it from the wall by rst raising up the inner or rear end of the shelf-plate to disengage the tenon 18 from its mort-isc 16, then springing the parts to force the upper end of the brace rearwardly to disengage the hooked lug from the upper end of the brace, then lowering the upper end of the brace to withdraw the tenon 1S at its lower end, then lifting the brace upwardly to withdraw the hooked lug, and tinally pulling the tongue of the shelf-plate wholly out of its socket in the wall-plate.

By my improvement the parts are cheaply constructed by cutting and shaping from sheet metal. They may be shipped in their knockdown form, so as to occupy but little space in transportation. They are readily put together for use and are very strong and substantial when in use.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not `wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in working my invention as may fairly come within the spirit and scope of the same.

I claim as my invention- 1. Aknockdown bracketconsisiing of wallplate, shelf-plate and brace, formed of separate pieces for locking together, the said shelt-v plate having the vertical tongue at its inner end and the said wall-plate having the vertical socket with walls for engaging both sides and both edges of the said tongue, substantially as described.

2. Aknockdowu bracket consisting of wallplate, shelf-plate and brace, formed of separate pieces for locking together, the said wall and shelf plates having at their meeting ends a tongue on one of the said parts and a tonguereceiving socket on the other of the said parts with registering screw-holes in the said tongue and wall of the said socket, substantially as described.

3. A knockdown bracket consisting of wallplate, shelf-plate and brace, formed of separate pieces forlockingtogether, the said brace having at each end the tenon 18 at one part and an outwardly-extended hooked lug at another part distinct from the said tenen, the said wall and shelf plates having connecting devices at their meeting ends arranged for permitting the inner end ofthe shelf-plate to be lifted within its connections with the wall plate, the said wall and shelf plate each having a mortise 16 for the said tenons Within which the said tenons tit closely, and slots 17 other than the said mortises, for receiving the hooked lugs of the brace, whereby the hooked lugs of the brace may be positively locked to the wall and shelf plates by lowering the inner end of the shelf-plate into its final position on the wall-plate, substantially as described.
